Water resources of the Yap Islands
Otto Van der Brug
1984, Open-File Report 82-357
The Yap Islands consist of four major islands, Yap, Gagil-Tamil, Maap, and Rumung. Of these, Yap Island has more than half the total land area, most of the population, and almost all of the economic development. The islands of Maap and Rumung together compose only 15 percent of the land...
Maps showing altitude of the potentiometric surface and changes in water levels of the alluvial aquifer in eastern Arkansas, Spring 1983
Joe Edds, Daniel J. Fitzpatrick
1984, Water-Resources Investigations Report 84-4264
The Mississippi River Alluvial Aquifer is a major source of water supply for irrigation in much of eastern Arkansas. Hydrologic maps of the potentiometric surface, water-level changes and depths to water in the aquifer, based on Spring 1983 measurements, are presented. The Mississippi River Alluvial Aquifer is comprised of Quaternary...
Hydrogeology of the Sulphur Springs area, Tampa, Florida
J. W. Stewart, L. R. Mills
1984, Water-Resources Investigations Report 83-4085
The Sulfur Springs area includes about 56 square miles in west-central Hillsborough County, Florida. The north-central part of the city of Tampa is highly urbanized; the north-west part of the area is rural or undeveloped. The area has numerous sinkholes, two of which are used as retention basins for urban...
Drainage basins in St. Johns County, Florida
Donald W. Foose
1984, Water-Resources Investigations Report 84-4232
The highest point in St. Johns County, Florida is only slightly above 65 feet above sea level and drainage divides are indistinct and readily influenced by cultural features. This report delineates some 80 drainage basins (or artificial equivalents to natural basins such as the Intracoastal Waterway) within the county and...
Land subsidence in the Santa Clara Valley, California as of 1980
J. F. Poland, R. L. Ireland
1984, Open-File Report 84-818
From 1916 to 1966 in the San Jose area of Santa Clara Valley, California, deficient rainfall and runoff was accompanied by a fourfold increase in groundwater withdrawals. In response the artesian head declined 180-240 ft. The land surface subsided 12.7 ft in San Jose, due to compaction of the fine-grained...
Average annual precipitation and runoff for Arkansas, 1951-80
David A. Freiwald
1984, Water-Resources Investigations Report 84-4363
Ten intercomparison studies to determine the accuracy of pH and specific-conductance measurements, using dilute-nitric acid solutions, were managed by the U.S. Geological Survey for the National Atmospheric Deposition Program and the National Trends Network precipitation networks. These precipitation networks set quality-control goals for site-operator measurements of pH and specific conductance....
Annual summary of ground-water conditions in Arizona, spring 1982 to spring 1983
Water Resources Division, U.S. Geological Survey
1984, Open-File Report 84-428
The withdrawal of ground water was slightly less than 4.2 million acre-feet in Arizona in 1982, which is about 1.2 million acre-feet less than the amount withdrawn in 1981. Most of the decrease in 1982 was in the amount of ground water used for irrigation in the Basin and Range...
Approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-84 and 1983-84, and measured compaction, 1973-84, in the Houston-Galveston region, Texas
Jeffrey L. Strause
1984, Open-File Report 84-140
This report, which was prepared in cooperation with the City of Houston and Harris-Galveston Coastal Subsidence District, presents data on water-level changes during 1977-84 and 1983-84 in the Chicot and Evangeline aquifers (figs. 1-4) and data on measured compaction 1973-84 (fig. 5). Water levels in about 550 wells were used to...
